I can read a raw of 640x480 bytes with: raw_file=open('sent_internal.raw') raw_image=raw_file.read()
It likely contains a lot of 0 values, black=0. The result above is a string of 242 characters. I'm guessing the 0's were ignored, and only >0 values were kept. If so, how do I get all 307200 bytes into a read? Whoops ... Ah, I missed 'rb'; however, I want to continue. I found the minimum value among the first 242 items to be 31 without the 'rb'. Among the 307200, I found it to be 150, which I believe is correct. That is, there are pixels in the image that are pretty bright. So what weirdness took place w/o the 'rb'? Why no 150? One more question, when I tried (no 'wb') read(size=307200), why di read balk at size, syntactically. -- Wayne Watson (Watson Adventures, Prop., Nevada City, CA) (121.015 Deg. W, 39.262 Deg.
